NWOT H&M Back tie yellow shift dress

It's a yellow halter dress, hits the knee with a bow to tie behind, in mint condition. It is LINED. I'm actually surprised why this dress is not sold yet. It's super pretty!! I bought it without trying or checking the size. It was one of those days. Goes well with brown or espadrille wedges. Can be worn as a formal summer office wear or for Sunday dinner brunch. Bought in HM for thrice the selling price. Reason for sale: Doesn't fit me.
